This blog discusses 3 different gun marking techniques, as well as the features that benefit quality control. Because no two guns can carry the same serial number, licensed gun manufacturers are obliged to record and track every gun produced and therefore, all gun marking or gun engraving performed at their facility, as well as the location of engraved gun parts.

Other gun markings such as model number, caliber or gauge, logo, manufacturer name and country of origin must also be engraved on the gun at a depth of 0.003”. The current required depth of engraving for a gun serial number is 0.003” in a print size no smaller than 1/16 inch. The ATF mandates that firearm serial numbers are engraved, cast or stamped on a gun frame or receiver in a manner that is not susceptible to being obliterated.
